Cancer can be said to be the disease with the highest clinical fatality rate. Most patients with early stage cancer have a high chance of being cured. This shows that cancer is not necessarily a terminal illness. As long as it is detected early and treated early, there is still a high chance of recovery. . As for the advanced stage of cancer, it is hard to say. Some patients can prolong their survival time after radiotherapy and chemotherapy, but only prolong their life.

Generally, there will be signals when a disease becomes cancerous, and these signals should be paid attention to.

1. Difficulty swallowing

Dr. Jin Chuan, director of the Fourth Department of Cancer Hospital Affiliated to Guangzhou Medical University, pointed out that when eating, there is retrosternal pain and a foreign body sensation in the esophagus. Even if you don’t eat, you will feel like there are vegetable leaves, fragments or rice grains attached to the esophageal wall. . After swallowing food, you will feel that the food goes down slowly or even stays in the esophagus. Long-term difficulty in swallowing may be a sign of laryngeal cancer, esophageal cancer and stomach cancer. You should receive X-ray chest X-ray or gastroscopy as soon as possible.

2. Unexplained weight loss

If a person's weight drops sharply in a short period of time and is accompanied by symptoms such as anorexia, repeated diarrhea and constipation, it may be a common symptom of lung, stomach, kidney and colorectal cancer.

3. Chest pain

If the tumor is located near the pleura, it often produces irregular dull or dull pain. Dr. Jinchuan reminded that when the tumor directly invades the parietal pleura, the pain is sharp and needle-like, and the symptoms will be aggravated when breathing or coughing.

4. Pain

Early-stage lung cancer patients rarely experience pain symptoms. Even if some patients have pain symptoms, the pain site is often inconsistent with the lesion site, which should be paid more attention.

5. Frequent fever or infection

In fact, fever is usually caused by influenza, pneumonia or other inflammations, but if the body has unexplained fever, they should be more careful at this time. Patients should pay attention to their own actual situation, choose Perform chest X-rays, CT scans, and MRIs.

6. Abnormal bleeding

Many people may not know that abnormal bleeding in the body is also one of the signs of cancer disease. For middle-aged and elderly people, if they have painless hematuria or difficulty urinating, they should be alert to the possibility of bladder cancer or kidney cancer. If you vomit blood and cough up blood, you should be concerned about the onset of diseases such as stomach cancer, esophagus cancer, or lung cancer.

Since people can know the status of their diseases through these cancerous signals, they must go to the hospital for examination in time when they find similar conditions. Don't regret it for the rest of your life because of the carelessness of the moment. Everyone has only one life, so you must cherish it.
